When winter throws cold and damp conditions your way, reach for the synthetic insulation of the men's Outdoor Research Neoplume Jacket. Designed to replace bulky fleece and weather-vulnerable down, the slim Neoplume can be worn alone or as a mid-layer. Weather-resistant insulation keeps you warm and moving in bitter cold, and compresses down into your pack when temperatures rise. The ripstop nylon shell repels the elements and has the durability to survive countless adventures.
